The issue with Hydrogen Fuel cells is it is only 40-50% full cycle efficient, vs batteries which can get to 80-90%.Hydrogen won't be green until nuclear is promoted. Only then fuel cells will be viable en masse
For some reason it is a boogeyman to environmentalists. They would rather have poisoned rivers and child labor in mines.
Guess too much money yet to be taken from the poor and given to the rich in subsidies to get away from it and promote nuclear
That's a big difference.
